In this state, setting value can be changed from 0 to 50 ° C by using up or down key. If there is no key input after the change, it will switch to the room temperature / humidity screen after a certain time and save the setting value. The stored value is preferably not erased even when the power is off.

Pressing the SELECT key once on the set temperature screen switches to the cooling deviation screen in which the cooling sensitivity temperature is displayed, which is detected when the room temperature rises above the setting temperature + cooling sensitivity temperature. Applying the contact signal of (10) to turn on the cooling operation relays (CS, C, CF) and start the cooling operation in the mushroom and plant cultivation accordingly. After that, the cooling operation proceeds until the internal temperature is equal to the set temperature. It stops automatically. Here, the air conditioning temperature setting range is 0 ~ 10 ° C. If there is no key input after the setting is completed, the set value is stored while switching to the room temperature and humidity screen after a predetermined time.

When the selection key is pressed once on the cooling deviation temperature screen, the heating deviation temperature screen is displayed. When the temperature of the room is detected to be lower than the set temperature-heating response temperature, the microcomputer 11 is connected to the terminal unit 10. The heating operation operation relay (RH) is turned on by applying the contact signal of, and the heating operation in the mushroom and plant cultivation is started accordingly, and the heating operation is automatically stopped until the internal temperature is equal to the set temperature. Here, the heating sensitivity temperature setting range is 0 ~ 10 ° C and pressing the up key once more at 10 ° C is displayed as "No Heating ..." to stop the heating function. Of course, inside the heating function is not required to continue pressing the up key until the subtitles, such as the above, if no key input after the setting is completed after 10 seconds to switch to the room temperature and humidity screen, the setting value is stored.

Pressing a selection key on the heating deviation temperature screen changes to the setting humidity screen displaying the setting humidity. In this state, the setting value can be changed from 20 to 99% by using the up or down key.If there is no key input after the change, the setting value is changed to the room temperature / humidity screen after a certain time and the setting value is saved.

The humidification operation operation relay (HU) is turned on by applying a contact signal of) and the humidification operation in the mushroom and plant cultivation is started accordingly, and the humidification operation is automatically stopped until the internal humidity becomes equal to the set humidity. Here, the humidification and humidity setting range is 1 to 30% and if there is no key input after the setting, the setting value is stored while switching to the room temperature / humidity screen for each room after a predetermined time.

Pressing the select key once on the humidification deviation screen changes to the dehumidification deviation screen in which the dehumidification humidity is displayed. When the internal humidity rises above the set humidity + the dehumidification humidity, the dehumidification operation in the mushroom and plant culture is started. The dehumidification operation continues until it is equal to the set humidity. Here, the dehumidification and humidity setting range is 1 to 30% and pressing the lift key once more at 30% is displayed as "No Dehumidi ..." to stop the dehumidification operation. At this time, it is preferable that the room without the dehumidification function is kept pressing the up key until the caption as described above. If there is no key input after the setting, the setting value is stored while switching to the room temperature / humidity screen for each room after a certain time.

Pressing the select key on the dehumidification deviation screen changes to the defrost operation screen displaying the defrost delay time. During the set time, the microcomputer 11 stops the defrost output and starts the operation. At this time, the room without using the defrost may be set arbitrarily because the above setting value has no meaning. Here, the defrost delay time setting range is 1-24 hours, and if there is no key input after the setting, the setting value is switched to the room temperature / humidity screen after a predetermined time.

When the selection key is pressed on the defrost delay screen, the defrost operation screen is changed to display the defrost operation time. After the defrost delay time (6 hours), the defrost operation is performed by the defrost operation time (5 minutes). In other words, when the microcomputer 11 applies the contact signal of the terminal unit 10 to turn on the defrosting operation relay DF, the microcomputer 11 proceeds with the defrosting operation in the mushroom and plant cultivation for 5 minutes. Here, the defrosting operation time setting range is 1-30 minutes, and if there is no key input after setting, the setting value is converted to the room temperature / humidity screen by room after a predetermined time.

Pressing the selection key in the defrosting operation screen changes to the ventilation delay screen displaying the ventilation delay time. During the set time, the microcomputer 11 stops the ventilation function and starts the operation. At this time, the setting range of the ventilation delay time is suitable for 1-240 minutes. If there is no key input after the setting, the temperature and humidity screen for each room is switched. The set value is saved.

Pressing a selection key on the ventilation delay screen switches to the ventilation operation screen displaying the ventilation operation time. After the ventilation delay time (20 minutes), the ventilation operation is performed by the ventilation operation time (20 minutes). That is, the microcomputer 11 applies the contact signal of the terminal unit 10 to turn on the ventilation driving relay (VT), thereby proceeding the ventilation operation in the mushroom and plant culture for 20 minutes. Here, the setting range of the ventilation operation time is 1-240 minutes, and if there is no key input after the setting, the setting value is stored while switching to the room temperature / humidity screen for each room after a certain time.

Pressing the Select key once in the ventilation operation screen changes to the humidifying delay screen displaying the humidifying delay time, which is operated by the set humidity and the sensitive humidity during automatic operation, while the humidifying delay time is ignored, while the manual operation ( S4) Since the humidifier is stopped and operated by the humidification delay time (20 minutes), it becomes a valid value when you want to operate manually. Here, the setting range of the humidifying delay time is 1-240 minutes, and if there is no key input after the setting, the setting value is stored while switching to the room temperature / humidity screen for each room after a certain time.

Pressing the Select key on the humidification delay screen changes to the humidification operation screen which displays the humidification operation time. In the automatic operation, the humidification operation time is ignored because it is operated by the set humidity and the sensitivity and humidity. After the humidification delay time (20 minutes), the humidification output is stopped for as long as the humidification operation time (20 minutes), so it is used as a valid value for manual operation. Here, the setting range of the humidification operation time is 1-240 minutes. If there is no key input after the setting, the setting value is stored while switching to the temperature / humidity screen for each room after a certain time.

Pressing the selection key once in the humidification operation screen is switched to the alarm status screen for viewing various alarm contents.

For example, N0 ALARM: no alarm is generated, FAN MG. Error: Overload of FAN MG., COMP1 MG. Error: Overload error of COMP1 MG, COMP2 MG. Error: Overload error of COMP2 MG, SENSOR T ROUBLE: Dry bulb temperature or wet bulb temperature sensor error.
